Gassy Moo

Gassy Moo is a non-aggressive critter that excrete Natural Gas. Gassy Moos do not appear on the asteroid, and have to be brought from Organic Mass by a rocket equipped with Biological Cargo Bays. They can be domesticated, but will not produce any eggs.

Behavior
Not much is known about the Gassy Moo due to its alien origin and nature. Presumably, their behavior in the wild is different, as they do not even reproduce in captivity, necessitating return trips to the source to poach more (a Moo lives for a maximum of 75 cycles). They are capable of flight and can survive in any atmosphere, or even lack thereof.

Moos eat Gas Grass directly from the farm tiles, much like Dreckos. A single Moo can eat 2 Gas Grass plants at constant growth. 11 Moos can sustain two Natural Gas Generators running at all times.

Gassy Moo is a peaceful critter and does not fight back when attacked by Duplicants.

Gassy Moo will be attracted by Airborne Critter Bait made of Bleach Stone somehow.

Farming economy

 * Sustaining the stable population requires regular expenses of rocket fuel.
 * Organic Masses can appear at different distances, so the amount of fuel can vary.
 * The feeding requires cooling Chlorine, which is energy-intense.
 * Lack of Chlorine Gas Vents can make farming challenging.
 * Chlorine Planet and Oxidized Planetoid can serve as alternative sources of chlorine, but both also require rocket trips.
 * With Pips it is possible to grow wild Gas Grass, although it increases the farm size in four times.
 * Gas Grass requires sunlight to grow, and therefore is either in competition with Solar Panel, or consumes energy by itself.

Since the main use of Natural Gas is limited to energy production, the resulting viability of farming Gassy Moos might vary.

In most cases, the expenses of farming Gassy Moos severely outweighs the benefits, and they are generally only useful for the 2 achievements that require the taming of one.

Farm construction
Natural Gas absorbs the most light out of the elements that are gases at the required temperatures, followed by Chlorine, Carbon Dioxide and Polluted Oxygen. Gases absorb more light at higher pressures. Luckily Oxygen absorbs no light. Therefore it is preferable to keep the plot with Gas Grass pressurized with pure oxygen, which will also push Natural Gas downside, where it can be collected.
